www.DataSheet4U.com Preliminary FM1112 Nonvolatile 3V Quad State Saver Features Nonvolatile State Saver Logic States Retained in Absence of Power Outputs Automatically Restored at Power-up Unlimited Number of State Changes Max tPD 50ns at 2.7V Max Frequency 1 MHz Low Power Operation Supply voltage of 2.7V to 3.6V 10 µA Standby Current Industry Standard Configuration Industrial Temperature -40° C to +85° C 16-pin “Green”/RoHS QFN Package Overview The FM1112 is an innovative FRAM-based device that stores inputs like conventional logic and retains the stored state in the absence of power. This product solves three basic problems in an elegant fashion. First, it provides continuous access to nonvolatile system settings without performing a memory read operation or using dedicated processor I/O pins. Second, it allows the storage of signals that may change frequently and possibly without notice. Third, it allows the nonvolatile storage of a system setting without the system overhead and extra pins of a serial memory. Functionally, the inputs are stored and passed to the output on the rising edge of the clock CLK. This unique product serves a variety of applications. Here are a few applications: ! ! ! ! ! Control relays or valves with automatic setting on power-up without processor intervention Interface to soft/momentary front-panel switch and indicator lamp. Capture switch settings and drive LEDs without processor intervention Replaces jumpers & control signa...
